I you are looking for passenger comfort about 1-2 hours is the max on the roadster. Of course I don't like to contend with grumpy passengers. The stock TBA seat and pillion would be better for passenger comfort. If comfort is the issue go with a Corbin or the Triumph touring is a little cheaper. I went with the roadster for looks and short distances with a passenger. A sissy bar would help with the roadster but I don't like the looks of the bars.
